Kraaij

I am a full Professor of ‘Applied Data Analytics’ at Leiden University and a Principal Scientist at TNO (The Netherlands Organisation for applied scientic research).

 

My research theme is ‘making sense of unstructured data’.  The two key elements here are unstructured data and sense making, representing the human element. This research area combines aspects from human machine interaction, design of algorithms, signal processing, semantic representations, reasoning, learning and abstraction.

 

I have worked in several domains: natural language and speech interfaces, dialogue systems,  information retrieval in several domains and modalities.
